What is the new equation of a line if it is shifted 5 units down and the slope is made twice as steep?

Back

If the original line is y = mx + b, the new line will be y = 2m(x) + (b - 5). For example, if the original line was y = 3x + 1, the new line would be y = 6x - 4.

What does a graph with a set-up fee indicate about the cost structure?

Back

A graph with a set-up fee indicates that there is a fixed cost incurred before any variable costs are added. For example, if there is a $10 set-up fee, this amount is charged regardless of the number of items ordered.

What is the domain of a set of ordered pairs?

Back

The domain of a set of ordered pairs is the set of all first elements (x-values) in the pairs. For example, for the pairs {(8, 2), (5, 4), (-2, -7), (-9, -9)}, the domain is {-9, -2, 5, 8}.

What does it mean for a function to be linear?

Back

A function is linear if it can be represented by a straight line on a graph, which means it has a constant rate of change or slope.
